Specification of Letters Patent. Patented flea-10', 19111. Application mana e, 1910. Serial No. 559,293.

To all whom "it may concern: r Be it knownthat I, HERMAN E. WHIT- INo, ofPalmyra, in the county of Wayne and State of New'York, have invented a f 5 certain new and useful Air Purifying Device for- Internal-Combustion Engines, of which the following is a specification.

My invention has for its object a particularly simple and efficient air purifying deconsists in the. combinations and v constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing, in which parts in\all the views.

Fi 'ure 1 is a vertical section of my air puri ing'device. Fig. 2 is a horizontal section on line AA, Fig. 1. Fig. 3 is a detail 20 view showin the manner of securing the bottom' plate of the filtering element.

This air purifying device comprises a receptacle having an inlet and an outlet for the air, and a filtering element detachabl:

251 secured 'in the receptacle and having passages'communicating with the inlet and the outlet.

1 is the receptacle having its upper side' open, the receptacle also having an integralw outlet conduit 2 at its bottom 3 or side oppo-- site the open side thereof, said conduit 2 projecting axially in opposite directions .from the bottom 3 and the part thereof ex tending into 'the receptacle, forming tov w gether with the bottom 3 and the lower porbody spaced apart from the cover and having' a central conduit 8 alined with the outopening through the top .of -thebody. Said body is also formed with filtering .cham-j bers 10 opening through its top and communicatin'gf at their lower or ends ii-with the chamber 4; of the receptacle, the

vice for internal combustion engines, and it like characters designate corresponding" ceptacle, and 7 is a filtering element integral wlt h the cover, said element comprising a let conduit 2 and coupled thereto by a lapping or interlocking mint 9, theconduit'8 iapart about the axis of the central condhit 8, the spaces between the filtering chambers I orming; air inlet passages 11 which com- =municate with the outer air through eonjduits'12 rising from the top of the body and registering with the passages 11 and opening through the cover 6. The side walls of the filtering chambers are usually radial tov the .axis of the central conduit 8. The cover 6, conduits 12, and body of the filtering element 7 are formed integral and constitute a unit which is removable for the purpose of cleaning, etc.

Preferably, the receptacle 1 is formed with internal threads 13, and the body of the filtering element 7 'is formed with peripheral threads 14 engaging the former threads,and the margin of the cover overlaps the edge of the receptacle around the open side.' Preferably, the walls of the filtering chambers tops thereof, forming shoulders 1-5 against which screens 16 abut which retainthefil'- :tering material, as wool, asbestos, and the like, within the chambers; Such material is prevented from falling from the chambersj 10 into the chamber 4 by means of a perforated plate 17 detachably secured to the inner end of the bod 9and formingthe bottom thereof, said p ate openings registering with the passagesJll and 0 are restricted at the lfiltering chambers being spaced equidistant u the perforated portions thereof extending 1 across the lower or inner ends; of the chainbers 10;

of catch, as the catch 1-8 carried by' the body and here shown as pivoted at l9'theretoi and? movableoniits pivot over the lower face of the plate. Usually, for the purpose of positioning and facilitating the. retaining of the plate 17 ili'position, the walls ot the passages-11 are prtwided with extensions or flanges at their lower ends which an the side walls of the openings of said plate and tend to center or guide. the plate into its operative position..- Oneof such flanges is shown at 20, Fig. 2. Ar suitable-register am The plate 17 is held in position means" 21 is carried'bythe'eover for opening and closing the conduits-12."

ing to? the carburetor, and duvingi thesuction' stiloke of the of' theengin'e'to" we are which the caltbureter; is attached, air p1.

--10l In operation, tlieF'outlet 20f the receptacle 1 is suitably coupled to the pipe lead-'- through the passages 11 to the catching chamber 4, where it impinges the water or other fiuid'held by the pad therein, then upwardly through the plate 17 and filtering chambers 10, and through the top of the body of the filtering element, whence it passes into the centralv conduit 8, outlet conduit 2, and to the carbureter.
